OptiPlex 3080 micro fan noise constantly rising and downing
In normal mode the CPU fan constantly change (speed?) noise insignificant. As I hear it: noise rising then in a 1 second back down and that happens all the time. It's annoyed very much.
In my experience, when idle, the fan is quite steady, no sudden changes BUT, this is using the BIOS 1.3.1
With any other BIOS version, the fan behaves in a different way, i.e. it spins at 1.800 rpm when idle which is veeeery annoying if you like silence, instead of the usual 800 rpm in Optiplex micros
It could be also any software installed using the CPU with that frequence
